The demand for durability as well as for water-miscible products and those that generate little or no VOC has resulted in the launch of a hindered amine light stabilizer (HALS), offered initially to customers in Europe and introduced this year in Asia.
Organic polymethyl urea matting agents impact the aesthetic appearance of a coating made with a metallic pigment in two ways: it reduces the flop index and increases the "sparkle" effect.
In order to achieve high-quality coatings, a pigment dispersion must be liquid, have an optimal particle size and be stable over long periods of time. During the grinding process, dispersing agents distribute and stabilize the smaller pigment particles, restricting re-agglomeration. These same dispersing agents help prevent flocculation of the pigment particles during storage and when mixed in a white-base, latex paint.
Successful incorporation of nanomaterials into optical display coatings relies on the core expertise of engineering finely tuned nanoparticles, dispersal in a variety of solvents and scaling these processes to commercial volumes.
Intelli-ion offers a safer, smarter way to replace traditional toxic chemicals and heavy-metal-containing substitutes. It can be easily incorporated into existing coating products, and could even enhance certain coating properties.
Shin-Etsu Silicones of America, Inc. has launched a new line of long-chain spacer type silane coupling agents that offer increased hydrophobicity and flexibility.
Special clays have successfully demonstrated their use as rheological additives in paint and coatings systems. Sepiolite, attapulgite and smectites make up a particular silicate subgroup in the clay family. All of them, under the appropriate processing conditions, produce gel structures that are capable of behaving as shear thinning and thixotropic fluids.
Maxemul reactive surfactants act as efficient emulsifiers providing colloidal stability and are chemically bonded to the polymer particles during free radical polymerization. The enhanced stability and mitigation of surfactant leaching during and after film forming significantly improve water resistance and barrier properties of the latex binder as a replacement of conventional surfactants.
This article is a comparison study using an accelerated weathering method to test different wood types pretreated with and without Eversorb SB in different co-solvents.
It is therefore important to evaluate different crosslinkers and understand their benefits and drawbacks in a given system to enable the formulation of a high-performance wood coating.
